摘要
With the rapid development of transgenic food, more and more transgenic food has been pouring into the market, and much attention has been paid to the edible safety of transgenic food. Transgenic soybean oils were studied by ICP-MS to detect 22 kinds of elements. The results showed that the contents of 7 kinds of macroelements range from 0. 13 to 12. 52 mu g . g(-1) in transgenic soybean oils, the range of the rest 15 kinds of microelements is from 0. 15 ng . g(-1) to 700. 00 ng . g(-1). The sequence of macroelement concentration is Ca > Na > K > Mg > Al > P > Si. There are 5 kinds of micoelemer ts whose concentrations were higher than 200 ng . g(-1), including Zn > Ba > Cr > Fe > Ti, especially Zn, Ba, Cr and Fe.
